Made famous by Art Deco masters and so highly prized, it's often sold by
the ounce, Amboyna burl is one of the rarest, most expensive and
difficult to obtain burl woods in the world! Taken from the Narra tree
and grows only in Southeast Asia. Some cuts can be as much as $500/
board foot. It was the first burl wood to be used by Rolls Royce for
dashboards.

A burl is a tree growth in which the grain has grown in a
deformed manner. It is commonly found in the form of a rounded outgrowth
on a tree trunk or branch that is filled with small knots from dormant
buds. A burl results from a tree undergoing some form of stress. Burls
yield a very peculiar and highly figured wood, one prized for its beauty
by many; its rarity also adds to its expense.
